I keep seeing this alarm icon and it’s timing randomly changes. I usually set my alarms at night. A bug maybe

rcward tried but still not working for me. Even in 4k zoom is not working properly instead of 8x it goes only 6x.

Firmware (bot) After this update, my phone seems to drain the battery very quickly. My SOT is very high. At first, I used to use it for more than seven hours on a single charge, but now it reaches 10% battery within 5 or 6 hours……

Orion_7u-op

Edit-whenever I charge my phone to 90 it drains ver quickly like 1 percent every 2 or 3 minutes until it reaches to 75 percent or lower than that and the slows down don’t know why

JP

Orion_7u-op that’s battery calibration issue… use your phone till 0% and charge it for 100% and keep it plugged for more 15-20 minutes and see if that problem is fixed or not

I have some events planned in this Jan and I was trying to check via essential search if it’s working and it doesn’t work, although I’ve given access to the calendar. Does anybody face this issue.

Also, the AI usage model also seems broken. I interacted with Essential search as well as Gemini and it doesn’t show

Dimas

Srivatsan-N same here, i hope Essential Ecosystem keep improving and provide the seamless integration in the future.

PatrykKupisz It’s worse that it only affects certain phones, cuz people who get lucky and dont get the random bugs love to call others “crybabies” for whining about issues until it finally hits their phone too. Nothing would be pressured into acknowledging issues better if everyone agreed something is wrong and reported it online

josegrind

Anonymous1123 I think it would be a good practice to raise a ticket by everyone who experiences a bug, i.e. excessive battery drainage, in order to make it more visible apart from a comment in here which maybe gets unseen or forgotten.

Look at this camera processing in Nothing 3a , it was not like this before don’t know what went wrong after this update. Plz help nothing team. It’s a huge color shift look at the preview and photo after processing

I’m struggling with a problem after the latest system update on my nothing phone 3a pro 5gWhen I connect it to my computer and want to share the internet via cable, it simply doesn’t respond, nothing happens. I can’t switch to cable sharing. Help!

Is it just me but i feel like my battery life have gotten worse with this update. After the update to nothing os 4.0 i felt a small improvement to the battery life but now it feels even worse that 3.2. Anyone else experiencing the same issue?

AbhirupDas_7dhnJnQanp

My Nothing phone 3a was working fine, however as soon as I updated it to the newest 4.0, the camera application became very slow and also the image became very processed, I do not the know the reason behind this, I have tried trouble shooting but it is not helping. If anyone know any solution, please help me.

Orion_7u-op

AbhirupDas_7dhnJnQanp I am also facing the same problem the processing has degraded after the update

Srivatsan-N

Why most of the icons are missing? I tried setting nothing icon pack as well as default, the icons showed above are all not present. Anybody has any idea on this?
